There have been around a half dozen Super Split copies in the last decade & they all have had problems. Not a single one has come close to the quality of the SS.
The Super Split is worth twice the money of any of the copy cats! I've been splitting around 15 cords a year for 10 years with a basic J model SS & absolutely love it!
I cut & split around the same amount of wood, mostly Oak. Did it by hand for 25 years. Bought a Super Split 10 years ago & Love It! I will never own a different splitter.
